Veronica plant named ‘Atomic Violet’

ABSTRACT

A new and distinct cultivar of  Veronica  plant named ‘Atomic Violet’, particularly distinguished by dark purple-violet colored flowers, compact habit, healthy foliage, and good mildew and rust resistance, is disclosed.

Latin name of genus and species of plant claimed: Veronica hybrida.

Variety denomination: ‘Atomic Violet’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Veronica plant botanically known as Veronica hybrida and hereinafter referred to by the cultivar name ‘Atomic Violet’. The new cultivar originated from an open pollination in 2003 in a nursery location in Haarlem, The Netherlands between unknown male and female Veronica hybrida plants.

The new cultivar was selected from the results of the open pollination in 2005 in Haarlem, The Netherlands. Asexual reproduction of the new Veronica by vegetative cuttings in a controlled environment in Haarlem, The Netherlands since the summer of 2008, has shown that the unique features of the Veronica are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Haarlem, The Netherlands:

-   -   1. Dark purple-violet colored flowers;     -   2. Compact habit;     -   3. Healthy foliage; and     -   4. Good mildew and rust resistance.

Of the many commercially available Veronica cultivars, the most similar in comparison to the new cultivar is ‘Darwin's Blue’, U.S. Plant Pat. No. 13,070. However, in side by side comparisons in Haarlem, The Netherlands, plants of the new cultivar ‘Atomic Violet’ differ from plants of ‘Darwin's Blue’ in at least the following characteristics:

-   -   1. Plants of the new cultivar have larger flowers, as measured         by corolla height and diameter, than plants of ‘Darwin's Blue’;     -   2. Plants of the new cultivar have a flower color that is         different from plants of ‘Darwin's Blue’;     -   3. Plants of the new cultivar have a foliage color that is         different from plants of ‘Darwin's Blue’; and     -   4. Plants of the new cultivar have stronger rust and mildew         resistance than plants of ‘Darwin's Blue’.

Of the many commercially available Echinacea cultivars, another that is similar in comparison to the new cultivar is ‘Purpleicious’, U.S. Plant Pat. No. 17,639. However, in side by side comparisons in Haarlem, The Netherlands, plants of the new cultivar ‘Atomic Violet’ differ from plants of ‘Purpleicious’ in at least the following characteristics:

-   -   1. Plants of the new cultivar have larger flowers, as measured         by corolla height and diameter, than plants of ‘Purpleicious’;         and     -   2. Plants of the new cultivar have a flower color that is         slightly different from plants of ‘Purpleicious’.

In addition, plants of the new cultivar ‘Atomic Violet’ are similar to ‘Atomic Pink’, pending U.S. Plant patent application Ser. No. 12/592,694. However, in side by side comparisons in Haarlem, The Netherlands, plants of the new cultivar ‘Atomic Violet’ primarily differ from plants of ‘Atomic Pink’ in floriferousness. Plants of ‘Atomic Violet’ have more flowers per inflorescence than ‘Atomic Pink’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show, as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical flower and foliage characteristics of the new cultivar. Colors in the photographs differ slightly from the color values cited in the detailed description, which accurately describes the colors of ‘Atomic Violet’. The plant was field grown for approximately 1 year in Haarlem, The Netherlands in an outdoor nursery location. The plant was transplanted into a container for photography purposes.

FIG. 3 illustrates a close-up view of the foliage of ‘Atomic Violet’.

DETAILED BOTANICAL DESCRIPTION

The new cultivar has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length, without, however, any variance in genotype.

The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England, 2007 edition, except where general color terms of ordinary significance are used. The data which define these characteristics were collected from asexual reproductions carried out in Haarlem, The Netherlands. The plant history was taken in September 2009 on 1-year-old field grown plants which were planted and grown outdoors in daytime temperatures between 14° C. and 28° C. and nighttime temperatures between 5° C. and 18° C. No pinching, growth retardants or photoperiodic treatments were used. Observations were made when the plants were in natural daylight conditions.
